An LCD device and a method of fabricating the device, in which the method includes preparing an insulating substrate including a gate wiring area and sequentially forming a gate wiring layer including a silver layer and a self-assembled monolayer on the insulating substrate. A mold mask is positioned above the insulating substrate, where the mold mask has a predetermined pattern to expose the gate wiring area. A self-assembled monolayer pattern is formed by printing the predetermined pattern of the mold mask into the self-assembled monolayer and a gate wiring pattern is formed by selectively etching the silver layer using the self-assembled monolayer pattern as an etching mask, where the gate wiring pattern includes a gate pad, a gate electrode and a gate line. The LCD device includes a gate wiring layer including a self-assembled monolayer and a metal layer of silver overlying an insulating substrate.
